Coalescence, also known as coarse granulation, is a process in which oily wastewater is passed through an installation filled with a filler (agglomeration information), and when the wastewater flows through the filler, the oil droplets are changed from small to large. After agglomeration and disposal, the oil content and the properties of slop oil do not change, but it is easier to remove the oil by gravity separation method. Coalescence and degreasing is a general term for coalescence and the corresponding sedimentation process. It has clear process characteristics and good application prospects. In recent years, China's oil fields have successively entered three stages of oil recovery. The ternary compound flooding is one of the advanced flooding and recovery technologies in the third oil recovery.It is made by injecting agents containing polyacrylamide, alkali, and active agents into the reservoir. A new technology to drive crude oil with aqueous solution to improve crude oil recovery. The production wastewater produced by the application of ternary compound flooding technology contains a large amount of polymers, alkalis and surface active agents, and the presence of these substances increases the stability of crude oil in water. According to the ternary composite floodback request for water injection quality, the polymers, surface active agents and other substances in the wastewater should be preserved during the disposal process, which limits the chemical degreasing methods, which also proposes the technology for the treatment of oilfield wastewater. Update request 2. As a physical and chemical method, coalescing degreasing method has attracted attention due to its unique degreasing mechanism.
The difference between coalescer deoiler and vacuum dehydration oil filter:
Suitable filter environment for coalescer degreaser:
1. Appropriately filter oils that contain a large amount of water, such as turbine oil, turbine oil, etc. 2. The water content is relatively large and a large amount of dehydration is required to show the dewatering performance. 3. The flow is divided into 32 liters, 50 liters, and 63 liters. , 100 liters, etc. according to customer's request 4. Can filter in explosion-proof places 5. Five-stage filtration system Vacuum dehydration oil filter filter environment:
1. It is suitable for filtering the oil containing trace moisture in the oil. It has a very high request for dewatering effect 2. The filter cleanliness can reach below 50ppm 3. It has functions such as degassing, deodorization and camel 4. The cost is relatively high, the effect is relatively high Better.
